Exchange Private Information Store is Priv.edb file. This file is the only copy of messages and other database items that are stored in users' mailboxes. When this file becomes corrupt, you may observe failure of typical database operations. For example, when you try to backup the database, Exchange may report an unexpected error while refusing to complete the operation. In such situations, it is essential that you delete the corrupted database file and restore from the last on line backup. But if backup seems to be invalid or unusable, you need to resort to exchange server recovery.
